Part of my object doesn't show it's texture in cycles
The problem is that you've plugged your Image Texture into the Normal socket of your Principled BSDF. It's not the way it works, you need at least to put a Vector &gt; Bump map between these 2 nodes, and ideally it's better to use a b&amp;w height picture, created from your original picture with a software like CrazyBump or else...
